Improved homebrew compatibility
We’ve had reports of some homebrew not running at full speed or not working at all, these issues have been resolved. As you’re probably aware, you can enjoy homebrew with SX OS for FREE! (without a license)

Added fuse burn protection
Some people are worried about burning their consoles’ fuses, preventing downgrades and possibly hindering upcoming emuNAND support. To put these minds at ease we now prevent these fuses from burning.

Support user cert in XCI
To play online your game (XCI) files need to have a unique certificate embedded. We now properly emulate these certificates, so dumps that have them embedded will be able to play online! Beware though, it is *not* advised to share a certificate with multiple people. Your best option is to make a backup of your own cartridges for the games that you want to play online. A way to do this currently is using WAIN v0.0.3, which can be found here.

Q: Is SX affected by the dreaded « battery desync » problem?
A: As far as we are aware this battery desync problem currently only occurs when running Linux on your Switch.
While extensively testing SX OS, including booting SX OS with AutoRCM we have not ran into a single battery desync issue ourselves.
SX OS itself isn’t based on Linux. We *do* allow people to run Linux (and other payloads) through our « external payload » functionality. This is at your own risk.
If we had to give the community a hint as to where to start looking into this « battery desync » problem we’d suggest looking into how the Fuel Gauge IC (MAX17050, I2C1 addr 36) is being used by Nintendo’s OS and by Linux.

Q: If I boot in OFW mode and play my original purchased game online, am I safe?
A: Yes, you are safe to play original games online in OFW mode.

Q: Does SX OS plays the original games in CFW mode?
A: Yes, it does.

Q: If I download eShop games to an SD card, can I also run SX OS on that card?
Or do I need separate cards for Nintendo eShop games and SX OS games?
A: You can use the same SD card.

Q: Is SX OS compatible with firmware 5.1.0
A: Of course. And as we stated before, it will be compatible with the next updates as well. We are offering a future proof solution.

Q: Will the SX OS for people who bought it ‘stand alone’ be delivered before the SX OS for people who bought SX Pro?
A: Not necessarily. SX Pro will be shipped in the days to come to distributors. SX OS will be unlocked a bit after the reviewers get their units (all reviewers receive SX Pro).
So depending on the speed of delivery to your distributor and then to you, SX Pro could come before SX OS stand alone. It probably will be very close.

Q: Why is there – and + symbols engraved in the SX Pro dongle?
Since USB-C devices can be plugged in either way, people are worried if dongle plugged in upside down, the + on left and – on right, and SX label facing down, that the Switch will blew up or get bricked, etc.
A: They are here just for cosmetic reasons. The – symbol is also the LED window.

Q: Yikes, those are two huge caps in render picture? Is that going to taser my Switch, damage my system, or zap me!
A: Super Cap’s actually (super-capacitor), 0.35F 2.7V, given the transport issues with Lithium based batteries SuperCap’s are fast becoming the go to temporary power source.
No zapping ( very low voltage ) and we limit the charge current to ~400mA peak for either USB port.

Q: Huh, two caps, how do they get ‘charged’? Do I have now and then plug my dongle into micro-USB cable to charge it, what happens when it runs out of power? — Why not battery instead? — Does it instead drain my Switch battery, what happens if I leave it plugged in.
A: The SuperCap’s are charged from either usb port ( USB-C or Micro USB ). The caps offer approximately 1 week standby time with enough energy left for one boot, or at least 5 successive boots without the opportunity to auto-charge. Charge to 80% is achieved (automatically) within 1-2 seconds of entry into the Nintendo start menu. We are working reducing that considerably … (see above for why not battery). Because we are powered by s-cap’s we have a very power conscious design.
Leaving the dongle in the console for more than a minute is pointless but will do no harm in any way to the dongle and drain very little battery ( currently we draw ~25mA but will work on reducing that considerably after ~1-2 minutes charge mode).

Q: Can I charge my Switch via dongle?
Using just micro-usb cable, removing the need of needing a proper usb-c cable.
A: Sadly no, our intent for the micro USB port was for charging the dongle and firmware updates, but might be something we will consider for future hardware revisions, thanks.

Q: There been reports of cables, and docks without that bricked the battery charging circuit, are we at risk with SX Pro solution?
A: No, simply because we do not support charging. The dongle uses both USB ports only for receiving charge.

Q: Is TX coming up with solution for those that leave their Switch always ‘docked’?
Its nice, that is portable, but some users never go ‘portable’, they are DOCK only fans, what about them?
A: If the demand is there, it is something we can develop.
